Abstract: 108,933. Thomas, L. L. Sept. 29, 1916. Self-driving machines.-Consists in employing the differences between the specific gravities of a liquid and a gas or of two different gases to displace continuously the heavier medium in a rotor so as to provide a preponderating unbalanced weight therein. A drum 1 carries radial cylinders 5 containing hollow pistons 6, which are connected in pairs by diametral external rods 13. The pistons, from the top down to an abutment 16 in the central portion of the drum, are shown in the outer position, their fellow ones on the left being in the inner position. The liquid or heavy gas within the drum is consequently almost wholly in the right half. The upper pistons on the right side float outwards, while the upper drums on the left side are prevented from doing so by a fixed quadrant 23 wherewith the coupling-rods 13 engage by means of lugs. In a modification, the pistons fit loosely and the bulk of the liquid is on the left, the pistons on the right being drawn outwards by a quadrant. In the modification shown in Fig .6, the mechanism is reduced to an annular tube 40 with the right half immersed in a semicircular chamber 45.

[Also in Group XIII] In a dielectric heater for treating non-conducting webs e.g. for drying wall paper or photographic films or for curing rubber webs, the web is guided as it moves between electrodes 8, 9 by guide members 20 at each edge from both sides to guide both marginal strips in alignment. The marginal strips extend into recesses in guide rails 18 of wood or acrylic resin and the top surfaces of the web are engaged by spring-loaded pressure bars 20 of acrylic resin, the pressure on the web or the distance of the bars 20 above the webs being adjusted by nuts 21 as shown. To minimise sagging or curling of the centre of the web, glass or other insulating rods 24 extend transversely between the guide rails 18 below and preferably above the web closer to the web than the electrodes 8, 9. The web may be guided in a path such that viewed edgewise of the web there is a knee in the path. Thus the web may first pass in an upward slope, then over a roller into a horizontal path and over another roller into a downwardly sloping path. The guide members may be co-operating pairs of conveyer belts of rubber or like flexible insulating material and may be entrained by the web or driven.. The web may be returned to adjacent the entry end and wound on a drum. The electrodes comprise transverse metal tubes 8, 9 connected in groups by metal strips 10 supported by insulators 12 on boards 14 adjustable by screws 17 to adjust the spacing of the electrodes from the webs. The lower sets 9 of electrodes may be adjusted in the direction of web travel by a threaded rod engaging a fixed nut. Air heated by passage over the valves of the R.F. generator may be passed over the web in counter-current to carry away vapours. Specifications 633,731, [Group XIII], and 744,323 are referred to.

Abstract: 1,017,590. Gyroscopic apparatus. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). April 10, 1963, No. 14345/63. Heading G1C. In a gyroscope wherein the rotor 4, Fig. 2, is mounted within a frame 1 by means of gas bearings 8, the rotor 4 is prevented from contacting the gas bearings 8 when the gyroscope is not operative by providing several caging devices which, as shown, comprise three fixed plugs 23 on the lower part of frame 1 and three movable plugs 24 on the upper part. Each movable plug 24 comprises a smoothly rounded end 26, Fig. 6, a cylindrical portion 25 and enlarged portion 27, pressed into engagement with rotor 4 by a spider spring 29. On supplying gas through ports 9, 10, 11, 12 to the gas bearings 8, the gas passes through passages 31 and, acting on enlarged portions 27 of plugs 24, tends to force them back against the pressure of springs 29. When the rotor 4 has picked up sufficient speed the combination of gas pressure acting on portions 27 together with the centrifugal force exerted by the spinning gyroscope forces plugs 24 out of engagement with the rotor 4. During manufacture the fixed plugs 23 may be of less height originally than bearings 8 to facilitate optically grinding the latter, the plugs 23 being subsequently built up by metalizing and electroplating. The pick-off arrangement comprises a mirror 15 viewed through window 16a and cavity 16. Specification 884,061 is referred to.
